Hydrogel agriculture technology uses insoluble gel-forming polymers to improve the water-holding properties of different soils, such as clays and sandy loams. This can increase water-holding and water use (up to 85% for sand), improve soil permeability, reduce the need for irrigation, reduce compaction, soil erosion , and leaching, and improve ...
The inorganic polymer (SN) x In polymer chemistry, an inorganic polymer is a polymer with a skeletal structure that does not include carbon atoms in the backbone. [1] Polymers containing inorganic and organic components are sometimes called hybrid polymers, [2] and most so-called inorganic polymers are hybrid polymers. [3]
In 1982, Munir Ahmad Khan led the establishment of the institute and its first director was Abdul Rashid who revolutionized the institute. The NIFA administers cobalt-60 radiation source, Laser absorption spectrometer and Atomic Absorption Spectrophotometry, Near-infrared spectrometer and Ultraviolet–visible spectroscopy.
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
Polyacetylene itself did not find practical applications, but organic light-emitting diodes (OLEDs) emerged as one application of conducting polymers. [9] Teaching and research programs in polymer chemistry were introduced in the 1940s. An Institute for Macromolecular Chemistry was founded in 1940 in Freiburg, Germany under the direction of ...
He also wrote Introduction to Materials Chemistry (John Wiley & Sons, 2008), Phosphorus-Nitrogen Compounds Cyclic, Linear, and High Polymeric Systems (Academic Press, 1972), Chemistry and Applications of Polyphosphazenes (Wiley-Interscience, 2002, and co-authored Contemporary Polymer Chemistry (Prentice Hall, 2003) with Fred Lampe and James Mark.
A generic polysiloxane. Polysiloxane, commonly known as silicone, is the most commonly commercially available inorganic polymer. [1] The large body of existing work on polysiloxane has made it a readily available platform for functionalization to create smart polymers, with a variety of approaches reported which generally center around the addition of metal oxides to a commercially available ...
